` FRAME non SEAT oUsHIoNs.

Original application filed January 22, 1923, Serial No. 614,133. Divided and this application filed January 2, 1926.

In the drawings:

Figure l is a sectional view along the line l-l of the frame shown in Fig. 2; and

Fig. 2 is a plan view, partially in section, of a frame constructed in accordance with the invention.

rlhis invention relates to frames for seat cushions and particularly to the lower frames of seat cushions for railway car seats and it is an object of this invention to provide a lower frame for a seat cushion that is rugged in vconstruction and may be economically manufactured. It is also an object of the invention to provide a lower frame for the seat cushions of railway car seats having integral pressed members. This application is a division of my application for a seat cushion, Serial No. 614,133, filed January 22, 1923.

Referring to the drawing, a lower frame l for the seat cushion of a railway car is illustrated comprising side members 2 and end member 3. The side members 2 and the end members 3 are composed of sheet metal and are joined at their ends by mitered joints. Each of the members 2 and 3 is pressed from a singley sheet of metal to form a substantially rectangular tubular memberl 4. The tubular member 4 is provided with a flat upper surface 5 which serves as a supporting base for spring members, one of which is illustrated in Fig. 1 of the drawing. The lower surface or wall 6 of t-he tubular member is olfset or displaced inward (upward) and thereby provided with a tapered groove 7 adapted to receive a tacking strip 8. IThe taper is so formed'in the groove 7 as to insure the holding of the tacking strip in position. One portion 9 of the lower vsurface 6 shown to the left of the groove 7, as viewed in Fig. 1, is formed at a higher level than the portion of the lower surface 6 on the opposite side of the tapered groove to take care of the covering for the seat cushion. The side edges of the metal sheet, which is bent to form the tubular member 4, are extended inwardly so as to project from and beyond the inner side or edge of the hollow body of the member 4, to form engaging flanges 10 and 11.

Pressed metal cross pieces or slats 12 are supported on the flanges l0 and 11 as shown Serial No. 78,834.

ance with the Yinvention it will be noted that each end and side member is formed from a single metal sheet and each member has a tapered groove formed in it for a tacking strip. The forming of a tapered groove insures the holding of the tacling strip securely in position.

lVhat is claimed is:

1. In a seat cushion, a substantially rectangular tubular sheet metal frame member having its bottom wall displaced inward in the form of a tapered groove, with the surfaces separated by the groove at diiferent levels, and a flange projecting from and beyond the side of said member. Y f

` 2. In a seatk cushion, a hollow frame having an upper surface and a bottom surface, the latter havinga tapered groove formed therein intermediate the sides of said frame v with the portions of the bottom surface on opposite sides of said groove flat and arranged at different levels.

3. In a seat cushion a frame comprising a top, a. bottom arranged substantially parallel with the top and provided with a tapered groove intermediate its opposite edges, a nailing strip substantially filling and being retained within said groove by the tapered sides thereof, said bottom having the portion on the outer side of the groove arranged at a higher level than the portion on the inner side of the groove.-

4. In a seat cushion, a frame having a top and a bottom arranged in parallel relation, said bottom being provided with a tapered groove intermediate its edges and having the portion on the outer side of the groove arranged at a higher level than the portion at the innery side of the groove, a nailing strip substantially filling the groove and being retained therein by the tapered sides thereof,

said strip being of a size suliicient to provide n an even surface from the outer edge of the frame across the `nailing strip.

5. In av Seat cushion, a frame -forined of a single piece of sheet metal providing top,

-I bottom and side sections, said bottom .being arranged in Substantially parallel relation to said top and having a tapered groove formed therein spaced from the side sections With the portions of said bottom on opposite sides of the groove larranged -a-t rdiLieren-1L levels, lo

the .edges of said sheet metal extending inwardly in superposed relation to provide a slat supporting flange.

In Witness whereof I have hereunto set my hand.

VICTOR IVILLOUGHBY.
